NA-IL OR SPIKE DRIVER.

SPECIFICATION forming part of Letters Patent No. 7 7 6,393, datedNovember 29, 1904:. Application filed February 29, 1904. Serial No.195,957. (No model.)

To all whom it may concern.-

Be it known that ALONZO H. H ARRIMAN, deceased, late a citizen of theUnited States. and a resident of Madison, in the county of Somerset, inthe State of Maine, and JAMES M. FEL- KER, a citizen of the UnitedStates, residing at Madison,in the countyof Somerset and State of Maine,invented new and useful Improvements in Nail or Spike Drivers; and we,MARTHA J. HARRIMAN, a citizen of the United States, residing at Madison,in the county of Somerset and State of Maine, administratrix of theestate of ALoNzo H. HARRIMAN, deceased. and JAMES M. FELKER, do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in nail and spike drivingdevices.

The object of the invention is to provide an implement whereby a nail orspike may be held, guided, and readily driven into places,

where it would be inconvenient to use a hammer directly on thenail-head, such as in close corners or under water in dam and fluinework, &c.

A further object is to provide an implement of this character which willbe simple in con struction, strong, durable, inexpensive, and welladapted to the purpose for which it is designed.

With these and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be more fully described, and particularly pointed out in theappended claim. In the accompanying drawings, Figure 1 is a sideelevation of the implement. Fig. 2 is a vertical sectional view on theline 2 2 of Fig. 1. Fig. 3 is a similar view taken at right angles toFig. 2. Fig. 4 is a horizontal sectional view on the line 4 4 of Fig. 3.Fig. 5 is abottom plan view of the closed jaws.

Referring more particularly to the drawings, 1 denotes a tubular casingor holder open at each end, as shown. In the upper end is inserted asliding plunger or driving-rod 2,

grooves 7.

which is provided on its upper end with an enlarged head or anvil 3, bywhich said plunger-rod is driven and which also limits the inwardmovement of said rod into the casing or holder. In one side of thedriving-rod or plunger is formed a vertically-disposed groove 4, whichis adapted to receive the inner end of a screw 5, which is screwedthrough the side of the casing and through a strengthening ring or band6 on the upper end of the same. By means of the engagement of the end ofthe screw 5 with the groove 4 the outward movement of the driving-rod orplunger 2 is limited. The inner end of said rod is reduced in diameter,as shown.

At diametrically opposite points in the outside wall of the tubularholder 1 and in the lower portion of the same are formedvertically-disposed grooves or channels 7, and in the lower end of theholder is formed a transverse slot 8, with which the lower ends of thegrooves 7 communicate. At the upper ends of said grooves are formedinwardly-projecting recesses-or sockets 9. In the grooves 7 and slot 8are arranged spring-arms 10, on the upper ends of which are formedinwardly-projecting lugs 12, which are adapted to engage the recesses 9,formed at the upper ends of the A ring or band 13 is slipped on the tubeand over the upper ends of the arms 10, thereby holding the same and thelugs 12 in place in the grooves 7 and recesses 9. The ring or band 13may be secured to the tube 1 by a set-screw or other suitable means.

On the lower ends of the spring-arms 10 are formed inwardly-projectingnail-holding jaws 14 and 15, which are normally held by the spring-arms10 in closed position below the lower end of the tubular holder 1. Thejaws 14 and 15 have inclined or beveled upper faces 16, by means ofwhich said jaws are forced apart by the lower end of a nail to permitsaid nail to enter and be held between the same while being driven. Thecombined exterior shape of that portion of the jaws below the end of thetubular holder when the same are in closed position is frustro-conical,as shown. The inner side 17 of the jaw 14 is V-shaped in horizontalsection and is adapted to fit into and engage a V-shape notch or recess18, formed in the inner side of the jaw 15.

19 denotes a vertically-disposed feed-slot formed in the tubular casing1 above the ring or band 13, and at its upper end said slot is enlarged,as shown, this slot being for the purpose of admitting nails to theinterior of the tubular holder 1.

To use the implement, the plunger or driving-rod is raised and a nail isplaced into the holder or casing 1 through the feed-opening 19 and dropshead upwardly through the holder and onto the inclined upper sides ofthe jaws 14: and 15. The lower end of the plunger is now engaged withthe head of the nail and the upper end or head of the plunger is struckwith a hammer or the like in the usual manner of driving a nail, theforce of the blows being imparted to the nail through the medium of thedriving-rod or plunger 2, thereby driving said nail between the jaws 14:and 15 and into the object to be nailed. The length of the driving-rodis such that when driven entirely in or until the inner end of the headengages the upper end of the tubular holder, the lower end of saiddriving-rod or plunger will be flush with the lower ends of the jaws andthe nail will have been entirely driven in.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

A nail and spike driver comprising a tubular holder having longitudinalgrooves in its outer side at one end and radial recesses at the innerends of said grooves, springs in said grooves, having lugs at theirinner ends engaging said recesses and having their outer ends extendingbeyond the outer end of the tubular holder and formed with jaws oppositeand normally closing said end of the holder, a ring secured on thelatter and bearing on the inner ends of the springs, and a driving-rodto operate in the holder, substantially as described.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
